Don’t find out about chemical container hazards the hard way
As an employer, your role in maintaining a safe work environment is not just important; it's urgent. The earth is heating up at an alarming rate. From May 2023 to April 2024, the earth experienced record-breaking temperatures for 11 straight months. This means that ensuring the safety of your employees, especially those exposed to hot temperatures, is now a pressing challenge.
Extreme temperatures, whether due to seasonal changes or the nature of work, can severely hamper the body’s ability to regulate heat, potentially leading to heat illness. This is not just a concern; it's a clear and present danger that should immediately spur you to protect your employees.
During warmer months, the temperature inside a shut-off vehicle can reach over 150 degrees Fahrenheit. Parking in the shade, opening the windows, or using window tints may only delay the temperature rise and an incident from occurring.
Consider the potential consequences if workers store flammable liquids in their vehicles without proper precautions. As the temperature rises, the container could rupture, leading to a potential fire if there’s enough flammable vapor and an ignition source is present. This scenario underscores the gravity of the situation and the need for immediate action. Here are four ways to avoid an incident from occurring:
- Store containers of flammable liquids properly,
- Inspect your vehicles for flammable liquid hazards regularly,
- Control sources of ignition, and
- Read and understand safety data sheets (SDSs).
Storage
Workers often utilize their work vehicles for various purposes, such as transporting items around the jobsite or storing tools and materials for future use. However, it's crucial to be fully aware of the potential hazards associated with certain containers found in company vehicles, namely hand sanitizer and marking paint. Being informed about these risks is the first step towards preventing incidents.
To ensure safety, it is recommended to store both hand sanitizer and marking paint containers properly when not in use. This can be achieved by utilizing approved storage options such as an approved safety can, a flammable cabinet, or a designated storage room. While these storage options may not always be practical or convenient to use in vehicles, it's essential to consider alternative measures.
Aerosols used for most marking paints are typically contained in thin aluminum containers. It's important to note that when exposed to elevated temperatures or sunlight, the pressure inside the aerosol can increase, potentially leading to container rupture and explosion. This can result in flying shrapnel that can cause injuries or severe damage.
On the other hand, hand sanitizer left in a vehicle does not have the potential to auto-ignite as the temperature inside the vehicle is not high enough for this to occur. However, if temperatures rise significantly, ignitable vapors from the hand sanitizer can be released. If an ignition source is present, the chemicals in the hand sanitizer or the flammable vapors could ignite. Therefore, handling and storing these containers properly is crucial to minimize the risk of accidents or injuries.
Inspection
It is important to find efficient solutions to address safety issues instead of adding additional tasks to workers' duties. One way to do this is by incorporating vehicle inspections into workers' regular routines. Determining the frequency of inspections to avoid complacency and time constraints can be challenging.
To streamline the process, inspections can be performed while workers are already performing other tasks. For example, after filling the vehicle with gas, workers can quickly check for flammable containers that require proper storage.
Additionally, workers can incorporate vehicle inspections into their pre- or post-shift routines or as part of their morning safety planning process. This way, they can identify and address container storage hazards before starting work activities.
Sources of Ignition
While vehicles are not typically considered hot work areas, it's important not to overlook them as potential ignition or fire hazard sources. Workers often see their company vehicles solely as a means of transportation and may not realize the safety risks they pose.
However, vehicles can indeed be fire hazards. Smoking inside the vehicle, a hot engine, using onboard generators, electrical circuits, and portable welding setups can all serve as ignition sources. A spark or heat transfer in the presence of flammable vapors and liquids could potentially ignite a fire.
SDSs
During jobsite training, workers are often taught how to read and apply information from Safety Data Sheets (SDSs). However, many workers lack a practical understanding of the content and how to utilize it for work-related matters.
Educating workers on identifying important details in SDSs, such as flashpoints, fire hazards, and storage requirements for chemicals they handle, is crucial. By ensuring that workers comprehend this information, they can effectively utilize it to prevent incidents and maintain a safe working environment.
Key to Remember
Containers in a hot vehicle can rupture, causing severe injury or damage. Use proper storage and handling practices to control ignition sources and avoid fires.
